UpdateTable

Updates the provisioned throughput for the given table, or manages the global secondary indexes on the table.

You can increase or decrease the table's provisioned throughput values within the maximums and
minimums listed in the Limits section in the
Amazon DynamoDB Developer Guide.

In addition, you can use UpdateTable to add, modify or delete global secondary indexes on the table. For more information, see Managing Global Secondary Indexes
in the Amazon DynamoDB Developer Guide.

The table must be in the ACTIVE state for UpdateTable to succeed.
UpdateTable is an asynchronous operation; while executing the operation, the table is
in the UPDATING state. While the table is in the UPDATING state, the
table still has the provisioned throughput from before the call. The table's new provisioned
throughput settings go into effect when the table returns to the ACTIVE state; at
that point, the UpdateTable operation is complete.

An array of attributes that describe the key schema for the table and indexes. If you are adding a new global secondary index to the table, AttributeDefinitions must include the key element(s) of the new index.
